Features
Everything your bastion needs
Built from the ground up for the D&D 5.5e Bastion rules — not an afterthought tacked onto a generic tracker.
Bastion Builder
Create your stronghold from 33+ official facilities. Track special facilities by character level, basic facilities by bastion size, and condition states from operational to destroyed.
Bastion Turns
Issue orders to every facility with a guided 3-step wizard. Recruit, Craft, Trade, Empower, Harvest, Maintain, or Research — all the canonical orders, with the right inputs for each.
d100 Event Engine
Roll the official Bastion event table at the end of each turn. Get color-coded outcomes — attacks, discoveries, magical, mundane, friendly visitors — with full event journals.
Campaigns & Co-op
DMs run campaigns; players join with an invite code. Share bastions with co-owners, see what your party is building, and keep the in-game calendar in sync.
Achievements & XP
22 achievements across 5 categories, 10 D&D-flavored levels from Novice Steward to Bastion Sovereign. Earn titles and badges as your domain grows.
Custom Facilities
DMs can homebrew custom facilities with full order builders, dice rolls, level gates, and special rules. Make the rules your own.

Questions
Frequently Asked
Is BastionForge free?+
Yes. The free tier lets you run a campaign with one bastion, four players, and one custom facility — enough for a full campaign. A premium subscription unlocks unlimited campaigns, bastions, players, custom facilities, full turn history, premium content packs, and removes free-tier caps.
Do I need an account?+
Yes. BastionForge syncs your campaigns and bastions across devices, so you'll need to create a free account. Email + password sign-in is supported.
Is this an official Wizards of the Coast app?+
No. BastionForge is an independent fan-made companion app and is not affiliated with, endorsed by, or sponsored by Wizards of the Coast. Dungeons & Dragons is a trademark of Wizards of the Coast LLC.
Which platforms are supported?+
BastionForge is built with Expo and runs on iOS and Android phones. A web companion is on the roadmap.
Can my whole party use the same bastion?+
Yes. Bastions support co-owners, so multiple players can share and manage a single stronghold together.
Does it work offline?+
Yes. BastionForge caches your data for 24 hours so you can keep browsing your bastion at the table even with no signal. Changes sync when you're back online.
